- qp.cluster.spheres_bad.check_NC(atom, metal)[source]¶
Check if a nitrogen / carbon atom in the first sphere is coordinated.
If the nitrogen / carbon atom is in the backbone, or it’s the nearest atom to the metal among all atoms in its residue, it’s considered coordinated.
- Parameters:
atom (Bio.PDB.Atom) – The nitrogen / carbon atom to be checked
metal – The metal atom (coordination center)
- Returns:
flag – Whether the atom is coordinated or not
